1996 PLYMOUTH VOYAGER SOFT BRAKE PEDAL AIR IN LINES

The master cylinder doesn't have a bleeding screw. Bleeding screws are located on each front caliper and the rear drum brakes. You'll need an assistant to press the brake pedal down on signal as you open the bleed screw slightly and close it back before they allow the pedal to return to normal position each time, until you've purged it through with new clean fluid. Fill up the master cyclinder frequently as you do this to assure it doesn't run dry. (If it does the master cylinder may be toasted.) Remember bleeding these types of cars is different than many others as it has dual lines, one for each side of the car. the bleed order is: LR, RF, RR, LF to get all the air out of the lines properly. Brake should be replaced every two years in humid or wet climates as brake fluid is hygroscopic... attaches to water vapor and stays in the braking system.

you will need to bleed all four brake lines

It's pretty much the exact same process just remove your abs relays/fuses
if the brake bleeding doesn't work it sounds like you may need a new master cylinder

Have you been bleeding with a vacuum bleeder tool or the conventional way. A vacuum bleeder gets out more air provided that everything else is done correctly.Like the correct wheel sequence depending on weather you have rear wheel anti-lock only or four wheel abs.Refer to a Haynes repair manual.

If you replace the wheel cylinders or brake calipers and did not bleed them properly, you most likely have air in the lines, If the rear brakes are drum brakes they need to be adjusted (if taken apart or new parts put on) or the pedal may sink when pressed.
1. If the brake pedal is soft when pressed down, the brake lines have air in them and need bleeding to remove the air.
2. a soft brake pedal can also be a bad master cylinder. Replace the master cylinder if the lines have been bleed correctly but the pedal is still soft or sinking when the pedal is pressed.

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

possible air pocket in the junction box . or plugged bleeder ports.completely remove the bleeder and see if fluid comes out it may take awhile.

It sounds like master cyl. is drawing in air causing prob. also another test would bee too bleed out and get pedal back, now step on pedal and hold firmly and see if pedal creeps near floor indicating innternal leaking in master cyl. also have some one pump bakes slowly aand look for air bubbles in brake res. after bleed out indicating master cyl. is drawing air upon release of pedal.

Have you had any work done on the brakes recently? 1st make sure the fluid level is ok. This can be either air in the lines (that's why I asked if any work was done on the brakes recently), or your master cylinder may need to be replaced. So, make sure there is no air in the system before spending $ on a master cylinder.

Try this unless you have done so....just about fool-proof!!!



THIS IS FOR A ONE PERSON JOB. IT IS A ONE PERSON BRAKE BLEED KIT.
